Will you give pen to lo at age of 16month old ? My mil keep on giving lo pen and I am not happy with it

My only concern with giving pens to 16 mo is their hands are too small to handle pens. Crayons are larger, and hence to train LO to have tripod grasp for future writing they need to grip larger item first. Another small concern is 16mo don't have the concept of what's right n wrong and they will be curious and start drawing everywhere with the pen.
